Title: Exhaust gas purifier for internal combustion engines
IPC: F01N3/28
Filed: 1964-08-20
Abstract: 1,077,446. Exhaust gas purifiers. WALKER MANUFACTURING CO. Aug.20, 1964 [Aug. 22, 1963; Feb.28, 1964], No. 34151/64. Heading F1B. In an exhaust gas purifier having concentric tubes 11, 9, 3, Fig.1 forming an inlet pipe 11, catalyst chamber 71, and outlet chamber 73, a portion of the tube 9 is unperforated and the space adjacent thereto forms a catalyst reservoir replenishing the bed 71 as the catalyst therein is consumed. The purifier is normally mounted with its axis vertical and the exhaust gases which enter through pipe 105 into the perforated tube 11, flow through the annular catalyst bed 71 to outlet chamber 73 leading to outlet pipe 129. The inner tube 11 is supported by perforated partitions 45, 47 in which it is slidable to permit expansion. In a modification, Figs. 8 and 9 (not shown) adapted to be mounted horizontally, the gases enter through pipes (272), (274), into chamber (308) and flow through pipe (284) into chamber (312) from which they flow through catalyst bed (314) into outlet space (310) and thence through outlet pipe (276). The tubes 270, 218, surrounding the catalyst bed are provided with louvres 318 over a portion only of their circumference so that the gases do not flow through port 316 of the bed which in practice is situated at the top of the device and forms the catalyst reservoir for the active part 314 of the bed.

Abstract: 878,418. Endless-band conveyers; escalators and travelators. STEPHENS-ADAMSON MFG CO. Oct. 27, 1958, No. 34331/58. Class 78 (1) In a moving sidewalk, escalator, or other endless conveyer of the kind including an endless load-carrying element having a grooved load-supporting surface, a self-aligning comb plate is provided at each terminal of the conveyer, each comb plate including projections received in the grooves of the load-carrying element and being mounted for movement sideways thereof, and spaced guide elements being secured to the comb plate and extending longitudinally to engage opposite sides of the loadcarrying element whereby the comb plate is caused to move laterally with the load-carrying element should the latter shift sideways. As shown, a moving sidewalk comprises an endless belt 21 provided with grooves 20. The comb plate comprises a series of vertically arranged plates 30, 32 arranged alternately, the upper edges of the plates 30 being at a level above those of the plates 32, and having pointed end portions 18 which project beyond the ends of the plates 32 and engage the grooves 20 in the belt 21. Each of the plates 30, 32 is provided with a pair of apertures by which the plates are mounted on a pair of sleeves 40. The ends of the sleeves 40 are threaded and a nut 42 engages the threaded portions to secure the assembly of plates in position thereon. Within each of the sleeves 40 is positioned at each end a bush 52. A pair of stationary rods 44 passes through the bushes of the two sleeves 40 and is secured by nuts 48 to a framework 46. A ball bearing cage 54, equipped with ball bearings 56, is interposed between a machined portion of each bush 52 and the corresponding rod 44, the cage 54 being held in position by retaining means 58. A pair of arms 22 are welded to the outermost plates 32 and extend longitudinally towards the conveyer belt 21. Rollers 70 carried on the ends of the arms 22 engage the outer edges of the belt 21. The ends of the plates 30, 32 remote from the conveyer belt 21 are grooved to receive a stationary platform 66. In operation, when the belt 21 moves sidewise, this movement is transmitted via the rollers 70 and arms 22 to the assembly of plates 30, 32 so that the comb plate follows the lateral movement of the belt 21.

Title: Coating process for protecting metals or metal alloys from corrosion
Inventor: WEIGEL JURGEN
IPC: C25D13/20

Abstract: 1,235,918. Electro-deposition of surfactant coating on metal. ELEKTROCHEMISCHE MATERIALBESCHICHTUNG m. b. H. GES FUR [trading as ECM GES FUR ELEKTROCHEMISCHE MATERIALBESCHICHTUNG m.b.H. & CO. K. G.] July 19, 1968 [July 21, 1967], No.34633/68. Heading C7B. To protect a metal or metal alloy from corrosion and/or to improve the adhesion to said metal or alloy of a lacquer coating or a coating of plastics material, the metal or alloy is connected as an electrode in an aqueous bath containing one or more surfactants and a current is passed through the bath to deposit on the metal or alloy a coating consisting substantially of surfactant material, the coating subsequently being subjected to a heat-treatment, typically in the range of 80 to 200 C. Preferably the aqueous bath contains 1 to 100 g/l of surfactant material such as fatty acid condensation products; sodium salts of alkyl sulphosuccinates or Turkey red oil; alkyl sulphates, phosphates or sulphonates; or alkyl aryl sulphonates as anionic surfactants which may be anodically deposited: N-alkyl pyridinium or alkyl ammonium salts as cationic surfactants which may be cathodically deposited: or polyoxyalkylene adducts as nonionic surfactants which may be deposited under either anodic or cathodic action. For anodic deposition an oxygen acceptor e.g. hydrazine may be included in the bath while for cathodic deposition a hydrogen acceptor e.g. hydrogen peroxide may be present in the bath. In examples metal panels of iron or aluminium are initially cathodically degreased prior to coating. For the formation of coatings on magnesium, aluminium or their alloys the bath also includes potassium fluoride and is used at pH 6 to 14. The coating may be effected in two stages, e.g. cathodic deposition of a cationic surfactant followed by anodic deposition of an anionic surfactant or vice versa, or electrolytic deposition of a surfactant followed by non- electro-chemical deposition of a further surfactant.
